Question

Two waves have frequencies 256Hz and 512Hz, but same amplitude. Compare their

(i) loudness, and (ii) pitch;

Answer 1

(i) LOUDNESS

∴ Amplitude of two waves is the same

∴ their loudness is the same i.e. in 1:1

(ii) PITCH:

Ratio of frequencies

256 Hz: 512 Hz

∴ Ratio of their pitch =1:2
